Mobile network refers to the use of mobile devices, such as mobile phones, PDAs or other portable tools to connect to public networks; mobile networks do not require fixed devices for access. Mobile network access still suffers from interoperability and usability issues; this is due to a variety of incompatible formats for the large amounts of information available on the Internet on mobile devices and partly due to the physical size limitations of small screens of mobile devices and other devices. cause.

What is mobile network

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

Mobile web refers to the method of using mobile devices, such as mobile phones, PDAs or other portable tools, to connect to public networks and achieve Internet access. Mobile networks do not require a fixed device to be accessed.

What is mobile network

Mobile network is generally not the same as mobile Internet.

Mobile network refers to browser-based Web services such as the World Wide Web, WAP and i-mode (Japan) using mobile devices such as mobile phones, PDAs or other portable tools to connect to public networks: no desktop computer required, There is also no fixed fixed connection.

However, mobile network access still suffers from interoperability and usability issues today. This is caused by various reasons such as incompatible formats for large amounts of information available on the Internet on mobile devices and partly due to physical size limitations of small screens of mobile devices and other devices.

Function of mobile network

1. Voice communication function is the most basic function of mobile phone; mobile phone will be able to provide mobile data service functions at various rates, such as MMS, LBS; data download and Internet surfing, online games, data multimedia, mobile application solution functions, provides communication interfaces with external devices, and supports multiple wireless access methods such as Bluetooth and WLAN.

2. Faster computing speed. With the improvement of chip computing speed and storage capacity, mobile phones can provide more powerful computing power, and real-time multimedia compression and transmission will no longer be a bottleneck.

3. Key technologies and technical routes: Mobile video phone

realizes real-time transmission of video and audio under mobile network conditions. Wireless networks have the characteristics of high bit error rate, narrow bandwidth, and large bandwidth jitter. Therefore, designing optimized video and audio transmission solutions based on the characteristics of mobile networks is the focus of our research.

What is a cellular mobile network?

The cellular mobile network we can see now actually refers to the 2/3/4/5G network we can use now. Public mobile communication systems all use cellular mobile technology. The difference between public mobile communication networks and WiFi is that one is a wide area network technology and the other is a local area network technology.

Cellular mobile is the foundation of mobile communication technology.

The initial public radio communications used technologies that provided strong coverage in large areas. At that time, the transmitting power of radio stations was very high, and a very high antenna tower was required to be built. The signal coverage area was also relatively wide, usually covering dozens or even hundreds of kilometers. The typical ones are the radio stations we listen to and Early television reception using antennas.

Cellular mobile communications propose the concept of a cell system. The original large area coverage is divided into multiple cells, and a base station is built in the center of each cell. In this way, each base station can cover a very short distance. The terminal can communicate with the nearest cell, which reduces the terminal's transmit power, enabling terminal miniaturization, which ultimately led to the advent of mobile phones.

Because the signal coverage of these cells is similar to a hexagon and the entire network structure is similar to a "cell", it is called cellular communication. The English name of cellular communication is Cellular.

Cellular communication is to replace the original large area system, so it is naturally a wide area network technology.

The large-area system is a communication technology with a large coverage radius. Cellular communication replaces the large-area system and needs to achieve the technical performance of the original large-area system, so it is naturally a wide area network technology.

The combination of cellular mobile communications and multiplexing technologies such as TDMA, FDMA, CDMA, OFDMA, etc. has formed our current mobile communications network.

What is the difference between cellular networks and Wi-Fi?

What is mobile network

WiFi is a local area network technology.

WiFi technology belongs to LAN technology in the communications industry, and it belongs to wireless LAN technology. WiFi technology was born to supplement wired LAN and is also considered an extension technology of fixed networks.

WiFi technology has evolved over the years, from the original IEEE 802.11b to the current IEEE 802.11ax. IEEE 802.11ax is also the popular WiFi 6.

What is mobile network

Cellular mobile communication networks and WiFi are used in different scenarios.

The cellular mobile communication network is a network that requires operators to be responsible for the construction, maintenance, and operation. It requires a large investment. The cellular mobile communication network not only ensures system capacity, but also has relatively high reliability and mobility. requirements, and these two are the shortcomings of WiFi technology.

In the 5G era, cellular mobile communication networks will compete with WiFi for some application scenarios.

5G is an era of industry applications. A large number of industry applications are located in indoor areas, which also makes mobile communication networks begin to enter the original application scenarios of WiFi.

In the 5G era, a large number of small base stations will be deployed indoors, which will pose a great challenge to traditional WiFi technology. In the future, WiFi products such as wireless routers may not need to be deployed inside homes, but will be provided by operators. Small base stations are responsible for users’ indoor data service needs.

In short, cellular mobile communication technology can be said to be the basis of current mobile communication technology. Any mobile communication network belongs to cellular mobile network. The cellular mobile we see on some devices now actually refers to us. These 2/3/4/5G networks are used.
